Gelneren [198K]

The common atrium is subdivided into a left and right atrium by an interatrial septum, which consists of two parts: the septum primum and the septum secundum that partially overlap.

What is septum primum and septum secundum?

  • The septum primum, which divides the right from the left, is a structure inside the primitive atrium.
  • In the direction of the endocardial cushions, this septum descends.
  • The foramen primum, a hole in this septum, keeps the blood flowing through the heart.
  • The foramen secundum develops as the foramen primum shrinks in size.

What is the purpose of septum secundum?

  • A muscular flap called the septum secundum plays a significant role in heart growth.
  • It has a semi-lunar form and develops from the atrium's upper wall to the right of the septum primum and ostium secundum.
  • It is crucial for the foramen ovale to close after birth.

Ivahew [28]

Limestone deposits can help researchers learn about what the area was like  thousands of years ago as Limestone can contain fossilized plants and animals.

  • The types of fossils found in limestone include coral, algae, clams, brachiopods, bryozoa and crinoids.
  • Limestone is a sedimentary rock made almost entirely of fossils.
  • Fossils are the remains of ancient plants and animals, like an imprint in a rock or actual bones and shells that have turned into rock. Fossils are found in sedimentary rocks and hold the clues to life on Earth long ago.
